    Safe, sure. Efficient? Not even close.

    It’s far, far more expensive than renewable energy. It also takes far, far longer to build a plant. Too long to meet 2030 targets even if you started building today. And in most western democracies you wouldn’t even be able to get anything done by 2040 if you also add in political processes, consultation, and design of the plant.

    There’s a reason the current biggest proponents of nuclear energy are people and parties who previously were open climate change deniers. Deciding to go to nuclear will give fossil fuel companies maximum time to keep doing their thing. Companies which made their existence on the back of fossil fuels, like mining companies and plant operators also love it, because it doesn’t require much of a change from their current business model.

      Australian politicians have been arguing about nuclear energy for decades, and with whats going on now, petty distracting squabbling while state governments are gutting public infrastructure

      The most frustrating thing is the antinuclear party is obviously fine with nuclear power, and nuclear armaments, just look at the aukus submarines

      labors cries about the dangers to our communities and the environment are obviously disingenuous, or they wouldnt be setting a green light for the billionaire robber barons to continue tearing oil and minerals out of the ground (they promise to restore the land for real-sies this time)

      Anyway, a nuclear power plant runs a steam turbine and will never be more than what, 30% efficient?

        Photovoltaic cells are even less efficient, I think they’re somewhere between 10-20% efficient. I think the way to go would be a solar collector, like the Archimedes death ray, but much much bigger.

          That is already a thing and it’s called concentrated solar power. Basically aim a shit load of mirrors at a target to heat it, run some working fluid through the target and use that to make steam to turn a turbine. There are a few power plants that use it but in general it has been more finicky and disruptive to the local environment than traditional PV panels would be.

          There are designs for a giant glass cone put in the middle of the desert. Air under the cone gets warmed and it rises up through a couple turbines on its way out of the device.

      Huh. So those of us that have always advocated for a nuclear baseline with wind/solar topping off until we have adequate storage solutions are climate change deniers? That’s new.

        Redox flow, sodium ion, iron air, etc.

        There are some 600+ current chemical-based battery technologies out there.

        Hell for me, once sodium is cracked, that shit is so abundant that production wouldn’t have many bottlenecks to get started.

        Pumped hydro? Or one of the many other non battery storage options, or just over production

          How viable is pumped hydro? It would be good if feasible, but last I checked, there were not enough places where you can install them.

            No, you’re right. It’s not an option for everyone. Which is why I mentioned that there are many other solutions which are similar and over production which is simpler and cheaper

                What? You don’t have Google? Options I know of (other than batteries and pumped hydro) : Compressed Air Energy Storage, Thermal Energy Storage, Fly wheels, Hydrogen, Supercapacitors, Gravitational Storage

                  The fact that you descend into complete science fiction should give you pause for thought. I doubt it will, but please think about how fantastical your proposed solutions are - “a massive lake of molten salt under every city” (I actually like that one!)…

                  1. It’s not easy to go over all options.
                  2. Many of these are largely theoretical, or for temporary storage. For instance, I don’t think fluwheels can store energy for months.

                    Nobody wants energy stored for months. Whatever storage is used needs to get through temporary decreases in efficiency. In places that use solar, that means from one afternoon to the next morning. In places that use wind, it means until the wind picks up. We’re talking storage on the order of tens of hours at the most.

                    Are you proposing that the sun may not shine and the wind not blow anywhere at all for months?

      Agreed, building a nuclear facility takes a lot of time and costs a lot of money. However… This doesn’t need to be the case at all.

      A lot of the costs go into design, planning and legal work. The amount of red tape to build a nuclear plant is huge. Plus all of the parties that fight any plans to build, with a heavy not in my backyard component.

      If however a country would be prepared to cut through the red tape and have a standard design developed for say 10 plants at the same time, the price and construction time would be decreased greatly. Back in the day we could build them faster and cheaper. And these days we build far more complex installations quicker and cheaper than nuclear power plants.

      The anti-nuclear movement has done so much to hold humanity back on this front. And the weird part is most people do think nuclear fusion plants are a good thing and can solve stuff. But they have almost all of the downsides nuclear fission plants have in terms of red tape, complexity and cost.

        You can’t cut the red tape. The red tape is why we’re able to say nuclear is safe.

        the weird part is most people do think nuclear fusion plants are a good thing and can solve stuff. But they have almost all of the downsides nuclear fission plants have in terms of red tape, complexity and cost

        Huh? Nuclear fusion doesn’t have any downsides or upsides. Because it doesn’t exist. We’ve never been able to generate net power with fusion. (No, not even that story from a couple of years ago, which only counted as ‘input’ a small fraction of the total energy used overall. It was a good development, but just one small step on the long journey to it being practical.)

        Being anti-nuclear was a poor stance to have 20, 30 years ago. At that time, renewables weren’t cost effective enough to be a big portion of our energy generation mix, and we should have been building alternatives to fossil fuels since back then if not earlier. But today, all the analysis tells us that renewables are far cheaper and more effective than nuclear. Today, being pro-nuclear is the wrong stance to take. It’s the anti-science stance, which is why it has seen a recent rise among right-wing political parties and media organisations.
